Basically this depends on your hardware. But personally for me as my criteria is accessibility for the most users.

1. Monero - can be mined just by cpu
2. Ethereum - can be mined just by gpu
3. Bitcoin - minable by asic

I think they will maintain. They might even be 2nd in terms of volume. Many exchanges now incorporates Ripple as one major cryptocurrency to fiat exchange just like the one that I use.

You can do self study which is based on your own intuition. Tutorial also tends to have a one on one correspondence. A classroom which is a more popular type address multiple audience which also give rise to social interaction with other students

I wonder how large the community of eth compare to bitcoin now. I see most of exchanges so far are using eth, and some is under buy its platform. Do you guys have any idea about the community of eth?
If it has large community now compare with bitcoin, why the price is still affected by bitcoin situation in the market?

I wonder this also. Ethereum has a higher community since it also incluse the ERC 20 tokens community and developers. I think this community is divided to two which are the finance community and forum community. Bitcoin takes those finance community.

What is your view about the shape of the earth?

I'm reading the comments and it seems all is right since no one votes for a flat Earth.

Of course the Earth is round. They have already proven it and I also proven it through some calculation and experiences like rockets trajectory, airplane displacement, etc.

I see a lot of bad news about crypto this year starting from hackers, scams, and fraud. can crypto be believed to be a safe investment? I am not sure if this continues to occur in Crypto.

How To Buy Monero?


The fees required with obtaining Monero will for the most part be lower on the off chance that you can buy straightforwardly on a Monero exchanging trade, for example, Kraken.

For huge buys, we suggest utilizing a trade. It can take a couple of days to send assets to a trade and get your personality checked with the trade.

That preference you are saying is a matter of trust. If your trusting the exchange for huge amount then us it. If your trusting someone's escrow as a trade partner you can trade then.

As long as the developers are active. If the cryptocurrency I hold is inactive, its nearing its death its time to sell. That is why its important to know current news about that coin.
